Use trout to deepen engagement in climate change, natural resources, and chemistry by raising native brook trout from eggs and performing on-site water quality assessments to find suitable release locations

2023 STEM Scholar
Buxton, ME Bonny Eagle Middle School

Erin’s Big Idea: 

Students will create a water quality and chemistry project focused on species loss due to human impact and climate change. They will adapt an existing Maine program – Trout Kids – and raise native brook trout from eggs in the classroom. Students will perform on-site water quality assessments to find the most suitable release location for the young fish. Erin will expand upon the chemistry topics in the Trout Kids program, and will use the trout to deepen engagement in climate change, natural resources, and chemistry units. Chemistry lessons will be structured on the elements, molecules, and compounds that pollute and disrupt habitats. Erin will loop a previously created tangential water filtration project with her Big Idea annually to deepen students’ understanding of the importance of clean water for humans and wildlife, and the myriad of threats to native species.

Objectives include:

  • A greater understanding of the importance of chemistry in daily life, and the lives of non-human organisms;
  • Testing and interpreting various water parameters like pH, conductivity, dissolved oxygen, and coliforms/bacteria using adult-grade chemical equipment;
  • Learning to explain the importance of clean, clear water to native trout populations, using specific water quality data to justify their explanation;
  • Making decisions based on collected data;
  • Learning proper trout husbandry, as well as general tank animal caretaking

Interesting Fact: 

Erin loves to spend time outdoors, and recently started rock climbing (indoors). Before teaching she did a variety of outdoor education work and taught skiing.

In her own words: “I love to garden and am in a never-ending battle with the invasive species in my yard. I am slowly replacing them all with native plants….I have access to a big greenhouse. I've been starting tons of plants with my students….I've loved watching them become independent in the greenhouse and have a lot of ownership over the project."
